SIGNALING APPARATUS.

Specification of Letters Patent.

Patented July 3,1906.

Application filed September 22,1906. Serial No. 279,596.

1' 0 (ZZZ whom/ it may concern: I

Beit known that 1, JOHN C. HUBINGER, a citizen of the United States, residing at Keokuk, in the county of Lee and State of Iowa, have invented a certain new and useful Improvement in Signaling Apparatus, of which the following is a full, clear, concise, and exact description, reference being had to. the accompanying drawings, forming a part of this specification.

My invention relates to signaling apparatus, and particularly to the adjusting mechanism therefor.

More particularly speaking, my invention comprises improved balancing and adjusting means for the armature of signali or signalcontrolling apparatus, such as a ternatingcurrent bells and relays, the invention being of particular importance and utility in connection with biased telephone-ringers in which the armature has heretofore been biased by means of spring mechanism. My invention contem lates the use of weights which may be a justably attached to one side of'the armature-pivot or to both sides thereof, so that the armature may be balanced or may bebiased in either direction to be selectively responsive to selective currents.

My invention will be best understood by reference to the accompanying drawings, in which- Figure 1 shows an ordinary polarized telephone-ringer and the application of the adjustable weights to the armature thereof, and Fig. 2 shows 'a polarized relay and the arrangement of the weights thereon.

The ringer-bell in Fig. 1. is shown as of the ordinary construction comprising the coils 1 and 2, mounted on the cores 3 and 4, connected by the yoke-piece 5. The olarizingmagnet 6 supports the armatureame 7, to which is pivoted the armature 8 before the poles 9 and 10 of thecores. The tapperrod 11 terminates-in the tapper 12, adapted for engagement with the bells 13 and 14.

From the ends of the armature extend threaded stems 15 and 16, which may be integral with the armature and on which the weights 17 and 18 may be moved longitudinally. Two or more weights are preferably used on each stem, so that they may mutually lock each other in position. If the bell is to be responsive to ordinary alternating current,. the weights are adjusted along the the same essential 1 parts.

stem to balance the armature, and if the weights 17 and 18 are equal they will be at equal distances from the arm aturepivot. If the bell is-to be responsive to pulsating current, for instance, of one polarity, the weights will be adjusted correspondingly to give the armature the proper overbalance or bias. The weights 17, for instance, will be moved to the end of the stem 15, and the weights 18 will be moved inwardly toward the armaturebody, or if the polarity to which the bell is to respond is of the opposite character theweights 18 will be moved outwardly and the weights 17 inwardly. Any degree of overbalance may thus be accomplished. For the bells near the source of ringing this overbalanc'e will be greater; but for distant bells, where the line resistance is comparatively great, the overbalance may be less to render the device more delicate.

Fig. 2 shows my invention applied to a po larized r lay which, like the device of Fig. 1, is of or inary construction and comprising The armature in this device, however, is not provided with a tapper-rod, but instead acts as a contact-arm for en agement with the contact 19 for closing a coal signal-circuit 20, containing the source 21 and the signaling device 22. As shown, only one set of weights 17 is shown and enga ing the stem 15, the armature being thus biased and adapted upon response to current-flow of one character to be actuated to engage the contact 19 to close the local circuit. To cause the device to be res nsive to currents of o posite character,

t e stem 16 only will c provided with weights and the contact 19 associated with the stem 15. As in-Fig. 1, both stems 15 and 16 may also be rovided with Weights which maybe relative y adjusted to give the proper bias and adjustment to the armature.

I do not wish to be limited to the adaptation of my invention to the devices shown nor do I wish to be limited to the exact arrangement thereof, as changes may readily be made without departing from the spirit of the invention.

I claim as new and desire to secure by Letters Patent- 1. In a signal-controlling device, the combination with electromagnetoles, of an armature subjected to the in uence thereof, signaling apparatus controlled by the movements of the armature, and a weight on said ments of the armature, and a weight at each secure threaded end of the armature havin engagement therewith, said weights being adjustable toward or-away from the annature-pivot.

4. In a signal-controlling device, the com bination with electromagnet-poles, of an ar. mature subjected to the influence of said poles, signaling apparatus controlledby the movements of said armature, a threaded extension from the armature at one side of its pivotpoint, and a weight having. threaded engagement with said extension to be adjustable thereon toward or away from the armature pivot whereby the end of the armature isnornially held in engagement with the corf responding pole-face.

5. in a signal-controlling device, the combination with. electromagnet-poles, of .an armature subjected to the influence thereof, signaling apparatus controlled by the movements of the armature, a threaded extension from the armature at each side of its pivot, a

weight having adjustable engagement along each extension w iereby the armature may be balanced or unbalanced to be held in engagement with the corresponding pole-face, and means for locking the weights in any adjusted position. 6.
